The FBI has not explained how Asch and Meltz are connected to Vale, but The New York Post reports that an undercover officer was used in investigating their plot.

NBC New York reports that the FBI came into contact with Asch when he responded to an online ad where someone had posted that they wanted help kidnapping, raping and kill his wife, sister-in-law and the sister-in-law's children.

The ad was posted in October and Asch met with undercover FBI agents to discuss a similar plot in recent months.

At two of the meetings, he brought items that he reportedly thought would be useful including a taser, a black ski mask, handcuffs, a hammer, pliers and forceps.

The agents set it up so that Asch conducted surveillance on a woman- not knowing that she was also a member of the undercover operation.

During one conversation with another meeting with agents, Asch reportedly said the female target 'had to die'.

Asch was the one who brought Meltz into the operation, saying that he wanted to help with the kidnapping of the woman.

'This is a fairly high-risk operation,' Asch said in a recorded conversation with Meltz.
